Greenhouse gas (GHG) emissions are primarily due to the exploitation of fossil fuel as an energy source, and one of the energy alternatives for the reduction of emissions is the use of renewable energy sources; one of these is solar irradiation conversion to useable clean energy. In the city of Istanbul, floating photovoltaic (FPV) installation started in 2017, on one of the lakes with an extensive surface area, Büyükçekmece, which supplies water to the city. To reduce evaporation losses and to generate electricity, two FPV prototypes were installed, with capacities of 9 and 90 kWp. Due to the location and climate of Büyükçekmece Lake, all system components including steel construction, metal sheet, maintenance way, connecting parts, and pontoons must resist extreme weather conditions, especially harsh waves and high wind loads. This paper is focused on a survey of the survival performance of the FPV system under real weather conditions without blockage of evaporation, just the reduction of it. Stress and strain tests were also applied to pontoons, one of the vital components for floating systems. The elasticity module, yield limit and tensile strength were evaluated as 0.42 GPA, 11.5 mPA, and 19 mPA, respectively. The wave height was calculated by means of four practical relationships, taking the lake’s distinctive characteristics into consideration. The electricity generation of 90 kWp FPV measured for June 2017 was 5189 kWh. The structural and electrical performance results from these systems in the city of Istanbul could be applied further to large scale FPV applications in water reservoirs nationally and internationally.

温室气体 (GHG) 排放主要是由于化石燃料作为能源的开采，减少排放的能源替代方案之一是使用可再生能源；其中之一是将太阳辐射转换为可用的清洁能源。在伊斯坦布尔市，浮动光伏 (FPV) 安装于 2017 年开始，在面积广阔的湖泊之一 Büyükçekmece 上安装，该湖泊为城市供水。为了减少蒸发损失和发电，安装了两个 FPV 原型，容量分别为 9 和 90 kWp。由于 Büyükçekmece 湖的位置和气候，包括钢结构、金属板、维护方式、连接部件和浮筒在内的所有系统组件都必须能够抵抗极端天气条件，尤其是恶劣的海浪和高风载荷。本文重点研究了 FPV 系统在真实天气条件下的生存性能，没有蒸发阻塞，只是减少了蒸发。压力和应变测试也适用于浮筒，浮筒是浮动系统的重要部件之一。弹性模量、屈服极限和拉伸强度分别评估为 0.42 GPA、11.5 mPA 和 19 mPA。考虑到湖泊的独特特征，通过四种实际关系计算波高。2017 年 6 月测得的 90 kWp FPV 的发电量为 5189 kWh。伊斯坦布尔市这些系统的结构和电气性能可以进一步应用于国内和国际水库中的大规模 FPV 应用。
